    Notes: [Auszug] IN the published account of the 1865 Rede Lecture, “On Radiation” (“Fragments of Science”, 1871), John Tyndall describes an experiment showing that a rise in temperature of an incandescent body augments the invisible radiation along with the visible. He tabulates the energy of the obscure ...

    Notes: [Auszug] IF, in a dust sample intended for microscopic examination, the number of particles per unit area were too large, some of the particles would overlap. Such ‘clumps’ would be counted as single particles instead of two, three or more, and the total count would be too low. The following analysis ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] ION exchange resins, in the hydrogen form, appear to offer several advantages as acid catalysts, such as the possibility of their continuous or repeated use without renewal, and their easy removal, by decantation or otherwise, from the reaction mixture. A paper on the subject has now been ...
